STEERING WHEEL AND METHOD OF FORMING SAME. APPLICATIQN FILED MAY 20. 1914.

Ft a 6 WITA/E88E8: l/VVE/VTOI? Q 4 v v .8 Czar/es l/ZZBGCX I U BY Arron/Em described in connection with the annulus i. The metallic rim section however, extends in a continuous piece through the annulus p.

While various forms of covering may be applied to the metallic ,rlm section,without departing from my invention, I--find it ironed while in but when a particularly smooth, hard sur-- .face is desired, the fibrous covering maybe engagement with the metal lic r1m section.

During the setting or hardening of the vulcanized fiber there is a tendency for it to contract. I therefore find it desirable'to form the covering of the rim of a plurality of segments, two being illustrated in the structure shown in the drawings. This will permit the contraction of the tubular casin'g without cracking or rupturing the same,

While the metal bands for securing the spider arms to the rimform suitable meansfor taking care of any inequalities at the adjacent ends of the fibrous tube, due to contraction. Another desirable methodof covering the metallic rim section is to spirally wrap the latter with a suitable cove'ring material.

With my improved construction of spider, thespider arms are formed of sheet metal st'ampingshaving their outer ends-as hereia'lb'efore described-attached to the rim and having their inner ends attached to the ,spider center P. The latter is formed of two: superimposed metal stampings Q. R having cylindrical hubs S suitably secured tg a bearing T. that receives the stem'of steering post. These sheet metal stamplngs have radially-extending arms U V between which'is arranged the inner end W of the spider arm, the parts U V and W being secured together by a rivet X. One of the stampings as V has the sides provided with flanges Y that are turned over the edges of the otherstamping. As shown in Fig. 6, the sides of the member T are provided with a groove Z forming a rectangular bearing portion A which is so arranged that the corners C thereof Wlll engage the /-shaped recess D in the end ofthe spider arm, thereby anchoring the latter against lateral play.

.As all the parts of the spider except the bearing for engaging the stem of the steer-- ing post, are formed of sheet metal stampings which are so constructed as to be readily assembled, the spider may be very cheaply manufactured-and also is comparatively light. If desired, the parts ofthe spider may be suitably grooved to add stiffness andstrength thereto.

' What I claim as my invention is 1. A steering Wheel rim, comprising a rim proper having a joint, a fastening member at the joint and an outer coveringof heat-insulating material substantially flush with the fastening member.

2. A steering wheel rim, comprising a rim proper, composed of a plurality of segments, an outer tubular covering of heat- I insulating material formed of.,segments' telescopically engaged with the segments of the rim proper, and means for rigidly connecting together the segments of the rim proper. I a

8. A steering wheel, comprising a "rim, spokes and hub, the inner ends of the spokes being inserted in sockets formed in the hub,

and a pair of sheet metal plates rigidly connee-ting. the hub and spokes, said plates relessees spectively having central apertures engaging the hub ends, and each having radially projecting clamping portions, forming pairs with the corresponding portions of the other plate to engage the inner ends of the spokes, and means rigidly connecting the coacting pairsof clamping portions with the spokes.

12. The combination with a 1111b piece provided with a circumferential groove having its bottom shaped to constitute a plurality of spaced abutments, a shoulder being formed atone end-of said hub piece, a plurality of spokes having their inner ends engaging with and of complementary contour to the abutment portions of said groove, a

pair of sheet metal members keyed on said hub, one at each side of the spokes and coacting to engage the inner ends of the spokes, one of said members being held in place through engagement ,With said shoulder,
